Efficient mine microseismic monitoring

International Journal of Coal Geology, 2005
Abstract During the past 20 years, the microseismic technique has grown from a pure research means for rockburst study to a basic industrial tool for daily safety monitoring at rockburst-prone mines. This article examines the important issues for efficient mine microseismic monitoring programs.

Microseismic Monitoring of CO2 Storage

Proceedings, 2012
Geomechanical deformation, if it creates and/or reactivates faults and fractures, can provide a leakage pathway for CO2 to escape the reservoir. By monitoring microseismicity in and around the reservoir, the risks of leakage can be assessed. Although it is a mature technology for monitoring hydraulic fracturing in tight gas reservoirs, microseismic ...

Microseismic Monitoring at a Limestone Mine

Geotechnical and Geological Engineering, 2008
Improving microseismic monitoring efficiency and accuracy at a mine requires an integrated effort. This article discusses a case study which demonstrates that the monitoring efficiency and accuracy can be drastically improved through optimally using the existing array, efficient techniques for signal processing and noise separation, and the advanced ...

Microseismic Monitoring Of Engineering Structures

2nd EEGS Symposium on the Application of Geophysics to Engineering and Environmental Problems, 1989
The monitoring of microseismic activity/acoustic emissions in engineering structures allows the detection and location of preliminary instabilities that always precede a structural failure. The primary advantage of this approach is that it can be used on operational structures and provide early warning of impending failure.

Ambiguity in microseismic monitoring

SEG Technical Program Expanded Abstracts 2011, 2011
Microseismic monitoring is synonymous with shale gas development in North America: experience with shale plays suggests a high degree of variability in rock properties, subsequent completion effectiveness, and ultimately gas production and EUR. There are several modes of acquisition currently in use to obtain microseismic information which is related ...

Challenges for microseismic monitoring

SEG Technical Program Expanded Abstracts 2011, 2011
We review important challenges in microseismic monitoring and interpretation of the microseismic events. We start with locations of microseismic events and the impact of temporal changes in velocity during hydraulic fracturing and consider effects of uncertainty in deviation surveys on both downhole and surface monitoring.
